Mirroring the root aggregates of the replacement nodes (MetroCluster IP configurations)

If disks were replaced, you must mirror the root aggregates of the new nodes on the disaster site.

  1. On the disaster site, identify the aggregates: storage aggregate show

    Example

    cluster_A::> storage aggregate show

    Aggregate Size Available Used% State #Vols Nodes RAID Status
    --------- -------- --------- ----- ------- ------ ---------------- ------------
    node_A_1_aggr0
    1.49TB 74.12GB 95% online 1 node_A_1 raid4,
    normal
    node_A_2_aggr0
    1.49TB 74.12GB 95% online 1 node_A_2 raid4,
    normal
    node_A_1_aggr1 - - - unknown - node_A_1 -
    node_A_2_aggr1 - - - unknown - node_A_2 -
    4 entries were displayed.

    cluster_A::>


  2. Mirror one of the root aggregates: storage aggregate mirror -aggregate root-aggregate

    Example

    The following example shows how the command selects disks and prompts for confirmation when mirroring the aggregate.

    cluster_A::> storage aggregate mirror -aggregate node_A_2_aggr0

    Info: Disks would be added to aggregate "node_A_2_aggr0" on node "node_A_2" in
    the following manner:

    Second Plex

    RAID Group rg0, 3 disks (block checksum, raid4)
    Position Disk Type Size
    ---------- ------------------------- ---------- ---------------
    parity 2.10.0 SSD -
    data 1.11.19 SSD 894.0GB
    data 2.10.2 SSD 894.0GB

    Aggregate capacity available for volume use would be 1.49TB.

    Do you want to continue? {y|n}: y

    cluster_A::>
  3. Verify that mirroring of the root aggregate is complete: storage aggregate show

    Example

    The following example shows that the root aggregates are mirrored.

    cluster_A::> storage aggregate show

    Aggregate Size Available Used% State #Vols Nodes RAID Status
    --------- -------- --------- ----- ------- ------ ----------- ------------
    node_A_1_aggr0
    1.49TB 74.12GB 95% online 1 node_A_1 raid4,
    mirrored,
    normal
    node_A_2_aggr0
    2.24TB 838.5GB 63% online 1 node_A_2 raid4,
    mirrored,
    normal
    normal
    node_A_1_aggr1 - - - unknown - node_A_1 -
    node_A_2_aggr1 - - - unknown - node_A_2 -
    4 entries were displayed.

    cluster_A::>
  4. Repeat these steps for the other root aggregate.
